HART--Jane. Warburg Realty acknowledges with great sadness the death of Jane Hart, who was associated with our firm for many years. Mainly active in and around the Newbury at 250 E. 87th Street, where she was a long time resident, Jane put a song in all of our hearts. A true lady who remained positive in every situation, her beautiful soprano graced many singing groups over the years, not to mention the halls of Warburg's offices. We extend our sympathies to her son, daughter, and grandchildren, with a special acknowledgement to Stephen whose courageous struggle and unflagging love filled her life with so much sunshine.
